Pro-only bank questions stay locked; this section mirrors only the 10 free daily questions already shown on this page.

Question 1 A user reports that a computer freezes only when one external drive is connected. Which troubleshooting step focuses on narrowing the cause?

Answer choices

  1. A. Isolating the problem
  2. B. Asking questions to understand user needs
  3. C. Documenting the issue for future reference
  4. D. Providing immediate solutions

Correct answer

Isolating the problem

Narrowing a failure to one device, application, setting, or condition is part of structured troubleshooting. Isolating the problem helps identify the likely cause before applying a fix. Asking questions gathers context, documentation records information, and jumping to immediate solutions can skip diagnosis.

Wrong-answer review

  • B. Asking questions to understand user needs: Asking questions to understand user needs gathers background, but the described step is narrowing the source of failure.
  • C. Documenting the issue for future reference: Documenting the issue for future reference records findings, but it is not the act of narrowing the cause.
  • D. Providing immediate solutions: Providing immediate solutions skips diagnosis and may lead to guesses before the issue is understood.

Extra learning features

Interview question

Q: Let's say a user reports their computer freezes consistently when they plug in a specific external hard drive. How would you approach troubleshooting this to determine the root cause? Strong answer: My priority would be to isolate the problem. I'd start by having the user try different ports, different cables, and different computers to see if the issue is specific to the drive, the port, the cable, or the original machine. I'd also ask them if they've recently updated drivers or installed any new software that might be interacting with the drive. If it's consistently reproducible with that drive, I'd suspect a driver conflict or a hardware incompatibility.

  • Systematic troubleshooting approach
  • Isolation techniques
  • Driver/hardware conflict consideration
  • Reproducibility testing
  • Asking clarifying questions

Caution: Immediately suggesting a driver update without further investigation. This skips the critical step of isolating the problem.
